How Farncombe compares
Small towns rarely get published solar figures, so here are the numbers for Farncombe. It is one of 47 Surrey towns we track, and it ranks 6th of 47 for solar yield, a town of 13,780 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,034 kWh per kWp a year, 2.83 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £924 of year one benefit, £247 of it from your own generation and £677 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Farncombe's own yield.
Planning applications here go through Waverley; nationally, the House of Commons Library classes Farncombe as a small town.
The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.

Generation is modelled from PVGIS satellite data for Farncombe's own coordinates (51.19872, -0.61802), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
SSEN and your Farncombe connection
Farncombe sits in Scottish and Southern Electricity Networks' Southern England licence area, so SSEN is the network operator (DNO) any solar panels or battery here are registered with.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SSEN within 28 days of commissioning, with no prior approval.
Larger systems go through G99 instead, applied for before installation. On timing: SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Beyond the panels: heating and car charging in Farncombe
A heat pump in Farncombe
Heating demand peaks when solar is weakest. In Farncombe, a 12-panel system makes about 240 kWh in December and 250 kWh in January, a fraction of its 810 kWh in July, which is why a heat pump here is costed on its tariff first.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Farncombe
Summer is where a car earns its place. In July, 12 panels in Farncombe make about 810 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Common questions about solar in Farncombe
How much electricity do solar panels make in Farncombe?
About 6,580 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Farncombe: 1,034 kWh per kWp, or 2.83 peak sun hours a day on average. July is the strongest month, at about 810 kWh.
What does a typical solar system cost in Farncombe?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Farncombe, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,580 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Farncombe, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Farncombe. A home system of up to 3.68kW per phase is notified to SSEN within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.
What happens to the solar I do not use in Farncombe?
Around £677 a year at 12p per kWh, for the roughly 5,640 kWh a 12-panel system in Farncombe exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Farncombe get in December?
December is the low point: about 240 kWh from a 12-panel system in Farncombe, on PVGIS data, rising to 810 kWh in July. From November to February the same system makes about 1,130 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Farncombe compares with its neighbours
The six closest towns we publish, run through the identical PVGIS query as Farncombe.

| Cranleigh | 1,050 | +16 kWh |
| Farnham | 1,020 | −14 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.

Guides worth reading before your call
Sourced, dated and written by us. The same ground we cover on your free call.
How long do solar panels last? 25 to 30 years, in practice
The panels outlast the inverter by a wide margin. Plan for that, not for cleaning.
Read the guide →Does a standalone battery actually pay back?
No panels means one job: buy cheap, use later. The tariff decides whether it pays.
Read the guide →Three phase and EV charging: what actually changes
Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
Read the guide →How much does a heat pump cost? The 2026 numbers, before and after the grant
UK median installed cost around £12,908, before the up to £7,500 grant comes off.
Read the guide →Why the best export rates always carry conditions
The top export rates are acquisition offers. Here is how to price the condition.
